Discussion on: How to migrate your library from Vue2 to Vue3

Thanks for the article:)

I have some follow-up questions:

  • Does that mean all you have to do to migrate an existing library is to do as the article suggest? Is there something else to do when migrating (I'm assuming you have to update some dependencies like Vue from 2.x.x to 3.x.x)?

  • Can I also use the next version the same way as the main version? Say I install the @next version but don't want to use it with composition API, will this work?

Hello Emmanuel, thanks for reaching out

  1. Yes, you have to update vue to 3.x version, and all related dependencies. This article covers adapting the installation of the plugin to the new standard in vue 3.
  2. Composition API is purely additive, so the library would work exactly the same if use with the Options API. It does depends if they're more breaking changes other than the installation added by the authors. In that case they should be reflected in a proper "Migration Guide" in the documentation.

I hope this clarifies your doubts. If you have any other, feel free to ask.

Happy coding.

Thanks for your reply. This reason I ask is that I'm planning on making a package and from what I have read, I can just go ahead and use the new standard and it will work for both Vue 2 and Vue 3, yeah?. This is what I need clarification on.

Since Vue.component isn't available for plugin in Vue 3, if I use app.component as you showed in the article and someone using Vue 2.x.x installs my package and then call it with Vue.use(packageName) in their main.js, will this process work?
